Side Effects and Complications
- Swelling and bruising: Common post-operative phenomena that typically subside gradually within 1 to 2 weeks.
- Infection: If sterilization during surgery is not rigorous or post-operative care is inadequate, infection may occur. Symptoms include redness, swelling, pain, and fever at the wound site, requiring prompt medical attention.
- Nerve damage: Facial nerves may be injured during surgery, leading to abnormal facial sensations or unnatural expressions. However, such cases are rare. If they do occur, most patients gradually recover within a few months.
- Skin necrosis: Excessive skin traction or compromised blood supply during surgery may lead to localized skin necrosis, although the incidence rate is extremely low.
Side Effects
In addition to the aforementioned side effects such as swelling, bruising, infection, nerve damage, and skin necrosis, the following conditions may also arise:
- Scar formation: Surgical incisions may leave certain scars, particularly in patients prone to scarring. Although incisions are usually placed in concealed areas, scar hypertrophy may still occur.
- Asymmetry: Post-operative facial asymmetry may occur due to factors such as the precision of surgical manipulation and individual differences in facial structure. If the asymmetry is significant, further corrective procedures may be required.
